Answer 2

let the weight of her mother be x kg.
Then,Weight of Lisa =x/2 kg
Total weight of both =48 kg

According to the question,

x kg +x/2 kg= 48 kg
=> 3x/2 kg= 48 kg
=>By cross multiplication, We have :
=>3x kg =96
=> x kg =96/3
=32 kg
Hence, the weight of her mother is x kg=32 kg
and weight of Lisa =x/2 kg =32/2 kg =16 kg
